And yet another question. . .this time, I would like to know what is/are the best source(s) of information regarding costume changes (books, videos, DVDs). How to make, how to use, etc. Basically, all of the 'ins and outs' of the genre.

Contact Betty Riley, Betty's Action Wear in Las Vegas (Do a google search). She builds the fastest costume change, and can tell you ANYTHING that you want to know about how to perform this. BUT, knowing how it is done and performing it, is two different things. It, like all illusions, takes practice, practice, practice!!!Good luck - Gerry
